Where to use CD4071

This C4071 is used in digital electronics for building Logic level circuits. This IC has 4 OR gates. So, if you require OR operation in an application with lower power consumption and a wide voltage range then you can use this IC. It is also used in designing Encoders and Decoders. You can also use this IC in all those applications where checking of more than events is required. If more than one event occurred, then some operation needs to be done for example checking the temperature or pressure of an industrial plant. You can detect temperature or variable through CD4071. If it exceeds the reference value, then the command will be set to the system to take action.

How to use CD4071 Quad OR Gate

As this CD4071 has a quad package that’s why it has eight inputs, two for each OR gate. All these inputs are supplied with signals. The pin 7 is connected to the ground of the circuit and pin 14 with the positive power supply. Before understanding the operation of this IC, let us suppose we have an OR gate with two inputs A and B. Then the output Z is given by the following Boolean equation:

Z = A + B
